Application filed August 28, 18;

To all who-m it may concern Be it known that I, CnAnLns. L. Sorrow, a citizen of the United States, residing at Oakland, in the county of lf'ottswsitemie and State of Iowa, have invented certain new and useful Pneumatic Qusl oning De vice for Vehicles, of which the following is a specification.

The object, of my invention is to provide a pneumatic cushioning device for vehicles tion, built in compactform which in applied to any kind. of vehicles and. plied to the axles. i

A further object is to provide snch 2-. tie-- vice which may be used with any kind of tires and in combination with springs.

A. further object is to provide a form of spring forming a part of my device and readily adapted thereto.

-A further object is toprovioie such a to vice which employs a pneumatic cushion around the axle casing and suitable rims for such cushion, said rims being adapted for being secureii to the spring.

My invention consists in certain details in the construction, arrangement and combination of the various parts of the device, whereby the objects contemplated at mined, as hereinafter more fullysetforth. pointed out in my claim and illustrated in the accompanying drawings. in which Figure 1 shows a side elevation of a part of a vehicle I equipped with a ivneumatic cushioning device, embodying my invention, the axle and the casing therefor being shown in section. Fig 2 shows a central, vertical, sectional view of my improved cushioning device taken on the line 2-2 of Fig.1.

In the accompanying drawings, I have used the reference numeral 10 to indicate the wheel of a vehi with any form o tire desired. The Wheel 10 is mounted on the axle 11 which is containcd within a (rising 12v Mounted on the casing 12 is a rim 13 ofimy desired form adaptml to hold a pneumetic tire. The rim 13 may be secured against longitudinal Specification 0! Letters Patent.

The mi'ews 14 are then inserted to prevent lateral. nwvement off the rim 13 on said axle (use. The pneumatic tire is mounted in the rim. 2.3 in the orclimiry way. The outer rim l7 then to 's-ned around the casing 15 of the pneumatic tire. The spring 20 is then mountccl on the rim 1'? and on the frame 1'3 of the vehicle.

My improved pneumatic cushioning iievice has the advantage of cushioning at the point where the frame is mounted on the axle in addition to any culinary cushioning device that may be used on the vehicle.

Its simplicity of construction is obvious. It may be used advantageously a. substitute for pneumatic tires in regions where, on so count of the condition of the roads or other causes pneumatic tires are impracticable.

The form of construction by which the spring is secured to the outer rim is believed to be novel and valuable.
